  • Fill the fuel tanks outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills.

  • Never fill the fuel tanks inside an enclosed trailer.

  • Never smoke when handling fuel and stay away from an open flame or where fuel fumes may be ignited by a spark.

  • Store fuel in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of fuel.

  • Do not operate without entire exhaust system in place and in proper working condition.

Danger

In certain conditions during fueling, static electricity can be released, causing a spark that can ignite the fuel vapors. A fire or explosion from fuel can burn you and others and can damage property.

  • Always place fuel containers on the ground away from your vehicle before filling.

  • Do not fill fuel containers inside a vehicle or on a truck or trailer bed, because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

  • When practical, remove equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

  • If this is not possible, then refuel such equipment on a truck or trailer from a portable container rather than from a fuel-dispenser nozzle.

  • If you must use a fuel-dispenser nozzle, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Warning

Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness.

  • Avoid prolonged breathing of vapors.

  • Keep your face away from the nozzle and fuel tank opening.

  • Keep fuel away from your eyes and skin.

Fuel Recommendations

  • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).

  • Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol). Using unapproved gasoline may cause performance problems and/or engine damage which may not be covered under warranty.

  • Do not use gasoline containing methanol.

  • Do not store fuel either in the fuel tank or in fuel containers over the winter unless you use a fuel stabilizer.

  • Do not add oil to gasoline.

Important: To reduce starting problems, add fuel stabilizer to the fuel all season, mixing it with fuel less than 30 days old; run the machine dry before storing it for more than 30 days.Do not use fuel additives other than a fuel stabilizer/conditioner.
